| description |
Precipitation is the start-up factor of multiple process in arid zones. To address the temporal and spatial variability of precipitation at north Patagonia is difficult given the large area of the region and the low measurement density. The objective of this work is to characterize temporal and spatial variability of precipitation, and to evaluate satellite derived rainfall products for this region. Based on six measurement stations’ daily records we calculated monthly, seasonal and annual precipitation, their averages and trends. In addition, we evaluated the relationship between these records with GPM and TRMM satellite products. Annual precipitation varied from 100 to 640 mm.year-1, with a 100 to 300 mm average in the last five years, and a downward trend in the last decades. We detected a downward trend in the average number of days with precipitation below 10 mm.day-1. The average daily precipitation showed a slight tendency to increase, as well as the frequencies of records greater than 10 mm.day-1. GPM was an acceptable estimator of the variability but none of the magnitude of rainfall. Precipitation variability updates, more detailed data and monitoring are needed. |

La precipitación es determinante de múltiples procesos en zonas áridas. Abordar su variabilidad es difícil en áreas extensas y de baja densidad de registros como la Patagonia norte. El objetivo de este trabajo es caracterizar la variación temporal y espacial de las precipitaciones, y evaluar productos satelitales de lluvia para esta región. Con los registros diarios de seis estaciones pluviométricas del período 1956-2019, calculamos la acumulada mensual, estacional y anual, sus promedios y tendencias. Además, evaluamos la relación de esos registros con los productos satelitales GPM y TRMM. La precipitación anual varió entre 100 y 640 mm.año-1, con una media entre 100 y 300 mm.año-1 en los últimos cinco años, y tendencia decreciente en las últimas dos décadas. Detectamos una tendencia decreciente en el número de días con precipitación por año y de las precipitaciones inferiores a 10 mm.día-1. La precipitación media diaria mostró una leve tendencia al aumento igual que los registros mayores a 10 mm.día-1. GPM representó mejor la variabilidad pero ninguno de los dos productos captó la magnitud de las precipitaciones. Es necesario continuar con actualizaciones, datos de mayor detalle y seguimiento de la variabilidad de las precipitaciones.
